Abstract
A method is disclosed for the conversion of a syngas to a liquid hydrocarbon product having a boiling range of less than 400.degree. F. at a 90% overhead and being a predominantly olefinic product, wherein the olefins have substantially internal double bonds. The method for accomplishing this stated result involves an improvement in the method for the conversion of synthesis gas by contacting the same with a catalyst composite comprising a mixture of a Fischer-Tropsch catalyst and a volume excess of an acidic catalyst, e.g., silica-alumina or a crystalline aluminosilicate zeolite and wherein the activity of the acidic component is balanced with the activity of the Fischer-Tropsch component so as to maximize the yield of desired olefinic product.
